"Find HEAD" button in svn:externals editor

I'm using version 1.8.7 of TortoiseSVN on 64-bit Windows 7.

I find the "Find HEAD-Revision" button in the svn:externals editor to
be *almost* useful. But because of this one issue, I can't ever
actually use it.

I'd like to use this button to determine whether I need to update my
externals definitions. I'd like to use it to automatically grab a
revision to use as the peg revision.

For this to work, the button should grab the revision of the last
change to the given folder or file. Instead, it grabs the revision of
the last commit to the entire repository containing the folder or
file.

I know that these peg revisions will technically give me the same file
content. But I can't just commit changes willy-nilly to the externals
definitions every time I check. And determining that an external has
not actually been changed after such a commit would require an extra
several steps to view the history of the folder or file in question to
figure out that the two revisions are actually identical.

Is there some use-case that requires the last committed version
anywhere in the repository? Or can this be changed to pull in the last
change revision instead? As the feature stands right now, it is pretty
much useless for the purpose of checking for updates on all the
externals at once, and automatically updating to the minimum required
version for each rule.
